Filed: 1952-06-16
Abstract: 713,230. Liquid or gas fuel burners. BOLLIGER, H. June 16, 1952 [June 19, 1951], No. 15039/52 Class 75 (1) A liquid-or-gas-fuel burner has an annular gas burner nozzle 10 which is surrounded by a cylindrical casing 3, 4 and 6 to which air is supplied through tangentially arranged inlets 1, 2 in order to impart a rotary motion to the air supplied thereto and the forward end 6 of which is conical so as to guide the air at a high speed around the annular nozzle 10 in order to effect a reduction in pressure around the annular outlet slit 16 in the gas nozzle 10 and in the internal space 57 thereof. Gas is supplied to the nozzle 10 through tangentially arranged ducts 13, 14. A liquid fuel nozzle 17 projects through an opening 5 in the rear wall 4 of the casing and is fed with liquid fuel through a pipe 19. An atomizing fluid such as compressed air or steam is fed to the nozzle 17 from a pipe 25 through a heater 22 arranged in the combustion zone and a pipe 20. In the arrangement shown in Fig. 3, liquid fuel under pressure is fed to a chamber 47 in the nozzle 17 and exerts a pressure on a spring loaded bellows 44 to move a rod 39 so as to open a fuel outlet orifice 36. Helical grooves 38 formed in a collar 37 mounted on the rod 39 impart a whirling motion to the liquid fuel. The atomizing fluid fed through a passage 33 to an outlet orifice 54 has a whirling motion imparted thereto by helical slot 30 formed in a flange 31 carried by a nozzle head 29. The rod 39, biased to the closed position by a spring 50, is prevented from completely closing the orifice 36 by means of a, collar 49 mounted on a screwed tail 43. The pipes 1, 2, 13 and 14 and the slot 38 and 30 are all disposed in the same direction of rotation. The movement of the rod 39 may be effected mechanically by means of levers, screws or the like connected with an automatic controlling device or manually when the fuel pressure remains constant. The bellows 44 may be replaced by a diaphragm. The heater 22 may be formed of helically or spirally wound tubes.

Abstract: 926,615. Nuclear power plant. ROLLS-ROYCE Ltd. June 2, 1960 [May 1, 1959], No. 15052/59. Class 39 (4). [Also in Group XIII] A nuclear reactor is used to superheat steam, of which a first part is fed from the reactor to two parallel steam generators where it is used to generate and superheat steam which is supplied to the reactor, and of which a second part is fed to a location of use, for example, in turbines where it is condensed, the condensate being returned to the steam generators by a single feed-water pump. The Figure shows a reactor 10 which supplies steam to steam generators 13; the generated steam is expanded through a nozzle and mixed with the steam from the reactor in a thermopump 17, and the mixture is returned to the reactor. The rest of the steam from the reactor is used in secondary steam generators 29, from which condensate is returned by way of heaters 51 and a pump 50 to the generators 13. The pressure at the pump inlet is held constant by means of a mixing chamber 73 connected to a pressurizing tank 76 to which are fed controlled amounts of steam and water. The pump is driven by steam from generators 29. In an emergency, water is forced from tank 130 into the reactor, after which coolant is allowed to flow by convection through tanks 131. Various auxiliary and emergency pumps 60, 65, 115 are provided, and so is a start-up steam generator 100. The pump 50 is driven by steam from generators 29. There is a water treatment plant 90 and a make-up water tank 83 which acts as an emergency condenser. Specifications 907,708 and 926,616 are referred to.

Abstract: 529,189. Making glass fibres. ALGEMEENE KUNSTVEZEL MAATSCHAPPIJ N. V. May 24, 1939, No. 15401. Convention date, May 24, 1938. [Class 56] Relates to the production of fine fibres of thermosplastic inorganic material, particularly glass, by drawing-out fine streams of the molten material by means of jets of gas or steam under pressure, as described in Specification 428,720. According to the present invention, the stream of glass and the surrounding gas, or steam are forced to pass through a constricted orifice close to the point of production of the stream in order to increase the tractive effort exercised by the gas on the molten material. In the construction shown, glass is melted in a furnace comprising a V-shaped bushing or container 11, Fig. 2, composed of platinum or refractory alloy and heated by the passage of electricity. The bushing is surrounded by insulating material 16, and the whole is enclosed in an airtight casing 19. The molten glass flows through perforations or nozzles 13 in the lower edge of the bushing, and the streams of glass pass through a slot in the bottom plate 28 of the casing. Gas or steam under pressure is supplied to the casing through a pipe (not shown) attached to its upper part, and the gas escapes through the slit and draws the streams of glass into fine fibres. The slot is formed by flanges 32 formed on two plates 27 slidably attached to the plate 28 and adjustable with respect to one another by means of screws 29. The furnace is charged with cullet or other material through a tube 23 provided with closely-fitting gates 24 to prevent loss of gas pressure. In a modification, the slot is formed by extended flanges 37, Fig. 3, formed on plates 35, and the thickness of the slot is determined by spacers 36 which are pivoted at their upper ends to one of the plates and constitute the end walls of the slot. The spaces 36 may be moved to form a tapered slot in order to increase the velocity of the glass and the surrounding gas or steam.
